When run in a work tree, tog remembers the work tree's base commit ID
at startup and displays a ~ or a * next to this commit in the log view.

Problem: If the work tree is updated to a different base commit while
tog is running, tog will keep showing a marker on the previously cached
base commit, even if the log view is reloaded with Ctrl-L.

With the patch below, tog updates the base commit marker during Ctrl-L.

While here, drop the unused repo argument of set_tog_base_commit().

ok?

 make tog log view reload work tree base commit info during Ctrl-L refresh
